2. Problem Description
The Canberra Health Insurance (CHI) was established recently. It has three branches in Canberra. CHI requires your team to design a database system to enable more smooth operation of the CHI by providing timely information to the CHI staff. The details of CHI branches are:
Branch name Address Telephone numbers
CHI Dickson 150 Camilla Way, Dickson, 2662, ACT 62016161
62016162
CHI Page 12 Page St, Page, 2614, ACT 62016163
CHI City 121A Future Ave, Braddon 2612, ACT 62016163
62016164
CHI database will record and store the data about each of its clients including first and last name, email address, postal address and home address (street number, street name, suburb, post-code, city, state), gender, date of birth, and type of health insurance a client has. The name (first and last name), contact telephone number and address (street number, street name, suburb, post-code, city, state) of client’s next-of-kin are also stored in CHI database.
CHI offers several types of health insurance. Health insurance policies are managed under development section of CHI. There exist several types of health insurances. These are namely Budget health insurance, Full cover health insurance, Extra plus health insurance. A client can take only one type of health insurance from CHI.
CHI health insurance s price per year is different for normal clients and senior clients of CHI. A senior client is a person who is over 65 years old. The details and cost of CHI health insurances are:
Health Insurance ID Health insurance type Cost (normal client) Cost (senior client)
M1 Budget $800 $400
M2 Full cover health $1200 $600
M3 Extra plus health $1500 $800
Each client is required to make a payment for their health insurance each year. Health insurance payments can be performed via the CHI branches or CHI website. Before a client takes a health insurance she/he is required to attend an interview with a staff member of CHI to discuss their health insurance needs. The interview takes only ten minutes.
Each client needs to book an appointment for their interview before they can take a health insurance by calling a CHI branch to book an appointment. The timetable and availability of each CHI staff member is recorded in CHI database and are available on the CHI website.
When a client takes a health insurance she/he is assigned a client number and her/his details are recorded. Every client is provided with a client number and the rules of CHI as well as the details of their health insurance.
CHI has several staff members in each branch. For each staff member the following data is stored in the database system of CHI: staff first and last name, staff number, position, gender, date of birth, email address, name of the section she/he works in, internal telephone number and branch number.
Each branch of CHI consists of three sections. These sections are: administrator section, development section and finance section. The information about each section is stored in the CHI database. The information about each section includes section name, location, email address, telephone and fax number.
CHI provides a gym for the use of their clients. The use of CHI gym is free of charge for CHI clients. CHI gym provides several classes. Each client needs to book for each class beforehand by calling the CHI on 1800811811 or using the GHI website to book a class. The timetable and availability of each class and the name of class instructor is recorded in CHI database and are available on the CHI website.
CHI gym has several instructors in its Gym. For each instructor the following data is stored in the CHI database system: instructor first and last name, instructor number, position, gender, date of birth, type of classes that an instructor can teach (i.e. Body Balance, Body Pump, Aqua aerobics or Yoga classes), internal telephone number, CHI gym number and CHI gym address.
Each instructor is limited to teach a maximum of three types of classes at any particular day. The instructor’s identity is established with their ID number and it is used to retrieve the details of the classes they teach. The details of each class (class number, Instructor ID number, date and time, details of the clients for each instructor) are stored in the CHI database.
